The BATSE experiment aboard CGRO monitored the whole sky in
the 20 keV - 2 MeV energy band continuously for 9 years,
from April 1991 until June 2000. Application of the Earth
Occultation technique and a Maximum-Likelihood imaging
method have produced all-sky significance and flux maps with
~mCrab sensitivity. In addition, a non-linear CLEAN
algorithm is applied to remove artefacts systematic of the
Earth Occultation technique. The latest all-sky source maps
and a summary of source detections are presented.

The INTEGRAL mission was launched October 17th 2002. The
ISGRI detector of the IBIS imaging telescope is ideally
suited to the detection and localization of soft Gamma-ray
sources in the 15 keV - 1 MeV band. IBIS has a field of view
of ~30 degrees and an angular resolution of 12'.
All-sky mosaics are generated by the summation of individual
science window images and can be further summed across
energy bands. Results are presented based on data from the
first 2 years of operations.

The long timescale of data from the BATSE experiment
combined and contrasted with the vastly superior imaging and
sensitivity capabilities of ISGRI present a wealth of data
to explore the properties of sources across the whole sky in
an energy regime which was last investigated by the HEAO 1
A4 experiment in 1979.
